Copy/Paste Function Not Working

I wasn't sure where to note this for Adobe staff/support, but I wanted to mention that after I use Dreamweaver for an extended period of time, let's say for the sake of a time reference after using Dreamweaver for 30 minutes to an hour, the copy/paste function will simply stop working. I can no longer copy/paste code with the shortcut keys, nor highlighting and right clicking.

Along with this, the program itself seems to just deteriorate after using it for an extended period of time altogether. I know this is general, but really, it just starts working poorly. One other example is that the live preview will just stop working even though nothing has changed as far as my end (i.e.: file locations, etc.) It just stops working properly.

There are a lot of odd end bugs like this I have noticed and I want to start making note of them to the appropriate staff/support, if possible.

Restarting the program is the only thing I can find that works, but it is only a temporary fix as these issues repeat themselves. This is obviously not a good solution though.

Thanks!
